Overview

Incremental Optical Encoder

The YUR48 series incremental optical encoder uses phase array technology with a large photoelectric gap for a longer service life. It offers differential output and a 500 KHZ response frequency, with a glass or film disc and conventional or cable saving wiring.

  • Phase Array Technology - high reliability
  • Photoelectric large gap - longer service life
  • High response speed - 500K
  • Resolution 1000 to 5000 CPR with differential output

Ordering rule

  1. YUR = series identifier
  2. 48 = 48 mm outer diameter
  3. 09 = bore (09 = 9 mm, 08 = 8 mm, below 9 mm on request)
  4. G = disc (G = glass, P = film)
  5. M = wiring (M = conventional, S = cable saving)
  6. 2500 = pulses per revolution (1000 / 1024 / 2000 / 2048 / 2500 / 5000 CPR)
  7. P4 = pole pairs (P2 / P3 / P4 / P5)
  8. C = leaf spring (C = d40 mounting hole, D = d55)
  9. 5V = supply voltage
  10. G15 = cable length
